If your loop is doing sensor fusion, motor control, or audio filtering, the FPU saves you from software-emulated float — a real cycle budget difference versus a Cortex-M3 like the STM32L151 series. The 64 KB SRAM gives enough headroom for moderate DSP buffers and a real-time OS heap. This part brings CANbus, multiple I²C and SPI interfaces, a QSPI for external Flash or RAM expansion, SAI for audio, and a full-speed USB. The 12-bit ADC has 16 channels and the DAC is dual 12-bit. With 83 GPIOs in the 100-LQFP package, you can wire up a TFT display, keypad, and several serial peripherals without an external port expander. The exposed pad is not present on this package variant, so all heat dissipates through the leads; keep the copper pad under the package solid and stitched to the ground plane with vias to help pull heat out. Coplanarity is typically good on LQFP, but inspect the leads for bent pins before placement. For BOM planning, there is no last-time-buy risk on this order code today.","metaTitle":"STM32L433VCT3 STM32L4 MCU, 80 MHz Cortex-M4, 256KB Flash","metaDescription":"STM32L433VCT3 32-bit ARM Cortex-M4 MCU, 80 MHz, 256KB Flash, 64KB SRAM, -40 to 125°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":"STM32L4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"80MHz","Series":"STM32L4","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"83","Core Processor":"ARM® Cortex®-M4","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L433","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.5100","priceTiers":[{"qty":1,"price":"$8.51000","currency":"USD"},{"qty":10,"price":"$7.68900","currency":"USD"},{"qty":25,"price":"$7.33160","currency":"USD"},{"qty":80,"price":"$6.36600","currency":"USD"},{"qty":230,"price":"$6.07991","currency":"USD"},{"qty":540,"price":"$5.54344","currency":"USD"},{"qty":1080,"price":"$4.82816","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6e323d1827cad59f98cd5297642b464c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L433VCT3/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L433VCT3 and STM32L433VCT6?","answer":"The difference is the package temperature range.
